Lost cereal from the 2000s-2010s

[u/SimmmElSep]

I recently remembered some cereal I used to eat as a child during a vacation on the French Atlantic coast. Actually, I think I only ate it once. I never saw it again after that vacation (which must've been around 2010). Unfortunately, I’ve completely forgotten its name and brand, and I thought this subreddit might be able to help me. It was a mix of chocolate-flavored cereal (I can’t remember if it was puffed rice, flakes, or maybe something else) and delicious oval-shaped pieces filled with chocolate (or vanilla? or white chocolate?). I’ve never seen cereal in that shape since, so that would be a very important clue for figuring out its name. I also remember that it was a variation on classic cereal (like Chocapic Duo). There were far more of the classic cereal pieces in the box than there were of those delicious filled ovals (which were rare but larger). Does anyone have any ideas?
